You say your DPID is actually 00:26:f1:3f:e4:80, but... I am guessing (and hoping) that you're wrong. I am guessing it's actually 06:d6:00:26:f1:3f:e4:80 (which is 492581376499901568, BTW).
So I think you're hitting a longstanding bug in discovery where it doesn't work right with DPIDs over 48 bits. This following message contains a patch addressing that, and I think it is a prerequisite for you getting this working: http://noxrepo.org/pipermail/nox-dev/2010-November/006705.html -- Murphy On Wednesday, June 22, 2011 02:18:17 PM Aaron Rosen wrote: > Hi Murphy, > > I managed to get it running but I can't seem to get it working correctly: > In discovery.py I've uncommented line 334 to print the following: > > print 'Sending packet out of ',longlong_to_octstr(dp), ' port ',str(port) > > From that I see: > > Sending packet out of 06:d6:00:26:f1:3f:e4:80 port 41 > Sending packet out of 06:d6:00:26:f1:3f:e4:80 port 36 > Sending packet out of 06:d6:00:26:f1:3f:e4:80 port 39 > > Port 41 is the port that connects to another OF switch > Also the DPID of my switch is really (00:26:F1:3F:E4:80), I'm guessing > the it's padding with 06:d6? > > Though if I print the dpid value in create_discovery_packet() it's > 06:d6:00:26:f1:3f:e4:80. > > Anyways: port 41 connects into an OF switch that has a dpid of: > 0e:83:00:24:a8:d2:b8:40 So I expect to see packet in events here > with my LLDP packet from port 41. > > > Using a modified packet print I print out the packets and the DPID > they came in on.
